r_o_b_s_o_n Offline Image Upload: Off p.1 #1 · Autofocus... F5 Vs. D700/D3 after trying various lenses on my D700 and F5.... and thinking about what I have read what people have to say about the D3/D700 autofocus... I just wondering if anyone else had noticed this.... While I have not compared tracking capabilities between the two autofocus systems... not really any doubt about it... the 51 point system will definitely do better than the F5's 5 point system.... but what I am wondering is... has any one thought that the F5's system.... and likely that of the D1 series.... do you find the F5 auto focus to be... more aggressive in focusing the lens? ie. Does it work better with screw drive lenses than the D3/D700? it just seems that the F5 will rake a lens from infinity to close focus, and back to infinity a lot faster than my D700??

camerapapi Offline Image Upload: Off p.1 #2 · Autofocus... F5 Vs. D700/D3 I do not know about the D700 AF because my experience with that camera is very limited but I compared the AF response between my old D2H and the brand new D300 and in my humble opinion the D2H is better.

andrewd01 Offline Image Upload: On p.1 #3 · Autofocus... F5 Vs. D700/D3 I think it's probably more a function of the size/power of the focus motor rather than the AF module itself. The bigger cams have room for more battery power and more powerful motors. So the D3 should perform similar to F5 for screw-driven lenses. In my opinion the difference between F5 and D700 is negligible, it would only matter if you have non AFS telephotos of 300 mm plus. cheers Sep 07, 2008 at 12:11 PM

dj dunzie Offline Image Upload: Off p.1 #4 · Autofocus... F5 Vs. D700/D3 It's a very interesting question, and like William I can only honestly compare anymore with the D2's. It's a very tight comparison in initial acquisition between the D300/D700 and D2's, but with sluggish non-AFS lenses with long throws (like macros) I might agree the D2's are a hair more powerful/quicker. The difference however is in tracking - where the new cams are definitely smoother and more consistently accurate in my experience. Sep 07, 2008 at 02:36 PM

Avi B Offline Image Upload: Off p.1 #5 · Autofocus... F5 Vs. D700/D3 I will say that my D1H seems to have a more torque-y (sorry not a real word but oh well) motor than the D2H. My 85 f/1.4 focusses very fast on the D1H. VERY fast. The D2H is almost as fast. And the D2H is faster than the D300 is based on my limited experience. This is all acquisition.

gugs Offline Image Upload: Off p.1 #6 · Autofocus... F5 Vs. D700/D3 this is my experience as well... acquisition seems relatively slow on the D3, compared to the F5.... when I use an AF lens (non-AF-S) I really have the impression that the F5 is much faster. And like I said in the beginning, I am still not convinced by the D3/D300 AF system, counter intuitive, no group dynamic... sometimes the slower AF of the D200 gives me more keepers thanks to the group dynamic, and for sports I see what I am doing, not really the case with the D3. Don't misunderstand me, the AF on the D3 is excellent but not as excellent as some people think on paper. If the subject does not fill the picture (and covers a lot of sensors), the AF is lost.

This is all acquisition. you are runing via the screw drive then itr is a torque positive device vs the built in ring motors on lens themselves. the ring drives do not need to be that powerful due to the area they encompess. and the way the function.

That comment made no sense to what was stated... He was comparing in cam AF motors. Not AF to AF-S motor technology. Sep 08, 2008 at 03:40 AM

Guy Hi Guy. I am interested in your experience, can you explain it a little bit more particularly the statement "...nd for sports I see what I am doing, not really the case with the D3" as I don't understand what you mean. I am also curious to understand why you see the lack of group dynamic (GD) as an issue. I use GD all the time on the D2 Series, but I find the Dynamic Area with 9 points on the D3 to effectively work the same. Not trying to disagree with you I just want to better understand your point of view. I have no view on the F5 anymore as I sold mine. The only observation that I would make is that I find the D3 to be more accurate than the D2 series in its focus acquisition in certain circumstances. In the D2 series if the subject was not large with respect to the focus sensor it sometimes would focus on the wrong part of the image. I find tracking in the D3 dynamic area mode to be excellent, and for what I do I don't see any difference with the D2's in this regard. I am far from sold on the 3D focus tracking. I have yet to get satisfactory results with it. Sep 08, 2008 at 12:04 PM
